Mod_perl 2 on Windows

Can anyone tell me why when I try to run the extra.pl file from the
windows configuration page
http://perl.apache.org/docs/2.0/os/win32/config.html#Registr y_scripts I
get the following error:

[Mon May 11 12:52:31 2009] [notice] Child 3608: Exit event signaled.

C:/Apache22/conf/extra.pl for server localhost:0, exiting...=20

extra.pl looks like this:

use ModPerl::Util ();
use Apache2::RequestRec ();
use Apache2::RequestIO ();
use Apache2::RequestUtil ();
use Apache2::ServerRec ();
use Apache2::ServerUtil ();
use Apache2::Connection ();
use Apache2::Log ();
use Apache2::Const -compile =3D> ':common';
use APR::Const -compile =3D> ':common';
use APR::Table ();
use Apache2::compat ();
use ModPerl::Registry ();
use CGI ();
1;

It's called from here:

PerlRequire "C:/Apache22/conf/extra.pl"

Alias /perl/ "/www/htdocs/perl/"
=20
SetHandler perl-script
PerlResponseHandler ModPerl::Registry
Options +ExecCGI
PerlOptions +ParseHeaders



Thanks
